Serial No.659,150.

The present invention relates to the manufacture of shoes having Louisheels, or heels of that general type, and is herein illustrated asembodied in a machinebspecially adapted for performing theoperation oflaying'the heel breastleaf orsplit portion of the sole against thebreast of a Louis heel after the heel has been attached to the shoe.

It is customary to cover the breasts of wooden Louis heels after theheels have been attached to the shoes by applying to eachheel breast athin leaf or flap which" has previously' been formed by splitting therear portion of thesole. Usually, for convenience in fitting the heelseat or for other reasons, the'sole is split along the shank to a pointsomewhat forward of the line where thebase of the heel breast will belocated. Acoating of cement or other adhesive is' applied to the innerface of the leaf and thereafter the leaf is manually laid against theshankand the he'el'breast with'th'e' aidof a bone or othersuitableimplement for rubbing and pressing the breast leaf intoplace. After theleaf has been thus manually laid in place, a heel breast clamp isemployed to clamp the f leaf firmly against the heel breast and hold itunder pressure duringthe drying and set ting ofthe adhesive. The layingof the leaf manually as above described is a comparatively slowoperation and considerable care is required if the leaf is to be'laldsmoothly throughout its entire area and the operation uniformlyperformed upon different shoes.

One object of the present invention is to" provide a practical machinefor laying the heel breast leaf, and one whichwill performthat-operation more quickly and efficiently than it can be'performed' byhand and in such F the Work to apply substantially rolling pres vided apressure-applying pad of rubber or other suitable yielding materialshaped to conform under compression to-the contour of the heel breastand adjacent shank portion.

of the sole, and means for operating said pad first to move itintoengagement with the;

forepart of saidshank' portion at its point of highest transverseconvexity then by con tinued movement of the'pad in' the same geii eraldirection to apply pressure progressively outwardto the opposite lateraledges of the" shank and rearwardto and along a portion of the'base oftheheel breast; and thereafter to; rock said pad about a substantiallyfiXed point adjacent to the base of the heel breast to cause the pad toapply pressure progres sivelyf upward, alongtheheel'breast to the treadface end 'of the heel, all for thepurpose of laying said" leaf smoothlyagainst the shank and heel breast. Preferably, the

pressure-applyingpad is secured to a carrier 1 movablymounted, upon acarrier support which is adapted for vertical swinging move-f ment tolower the pad into engagement with the shank portion of'alasted shoesuitably supported beneath the pad. After this downward movement of thepad has been of fected to lay the leaf along the shank of the sole, asliding movement in an arcuate path is imparted tothe pad carrier tomove it rela tlvely to theswingmg carrier support for the purpose ofrocking the pad to lay'the leaf against the heel breast. The illustratedpad carrier and carrier support are operated by means of'mechanisrncontrolled by a onerevolution clutch sothat at each cycle of oper ationsof the machine the pad is caused to perform a single leaf-layingoperation and then to be retracted from engagement with the shoe topermit the removal of the shoe which hasbeen' operated upon and itsreplacement by a shoeto be operated upon.

The illustrative machine comprises a suport 2 for a lasted shoe, abackrest 4 for the heel of the shoe, anda movable pad 6 for layingthe heelbreast leaf. These parts are arranged in front of a hollow head or frame8 within which is mounted mechanism for op- The head or frame 8 issecured to the upper end of a standard 10 and the pad-operatingmechanismis driven by means of a motor 12 which is supported upon abracket or shelf 14 that is adjustably secured to the rear of the head8. V

The support 2 for the lasted shoe consists of an upright arm formed witha rearwardly curved lower extremity which is rigidly secured to thefront of the head 8. A last pin 16 surmounts the arm or support 2,adapting the latter to support a last such as indicated at 18 in Fig. 1.The last 18 is fitted within a shoe 20 having an attached Louis heel 22and a heaf or flap 24 which has been split from the sole 2 5 of the shoeand is to be utilized to cover the breast of the heel.

To support the heel against the backward thrust of the leaf-laying pad6, the back rest 4 consists of a roller of a diameter such thatthecurved face. of the roll will substantially conform to the concaveportion of the.

cry of the back rest roll 4 is hollowed or concaved. in the direction ofthe axis of the roll, as shown at 26 in Fig. 3, to conform substantiallyto the horizontal or transverse convex curvature of that portion at therear of the heel which is engaged by said roll. The

roll 4 is mounted to turn freely upon a pin 28, the opposite ends ofwhich are fixed in the arms of a yoke 30. The yoke 30 is mounted for alimited amount of vertical swinging movement to enable the back restroll to adjust itself readily to heels of different heights; To this enda stud 32, which extends rearwardly from the closed end of the yoke 30,is received within a split sleeve or socket member 34 and is rigidly butadjustably clamped therein by means of a binding screw 36 arranged tocontract the sleeve about the stud. The sleeve or socket member 34 isarranged to rock about an axis perpendicular to the length of the stud32 and to this.

end a bearing lug 38 depending from said sleeve is pivotally mountedupon a rod 40 which is parallel to the axis of the roll 4 and issupported at its opposite ends in bearings 42 formed on the frame 8. Tolimit the downward swinging movement of the back rest roll 4, a stoplinger 44 projecting forwardly from the bearing lug 38 is arranged toengage an adjustable abutment in the form of a screw 46 which isthreaded into the frame 8 and provided with a suitable lock nut 48 forbinding it in adjusted position. After loosening the lock nut 48, thescrew 46 may be turned to vary the lower limit of vertical swingingmovement of the back rest roll and thus to vary the position of thelatter when it is idle, i. e., when no shoe is present upon the support2. This adjustment should be varied in accordance with the height of theheels to be operated upon, it being desirable that the roll 4, whenidle, should be supported in a position lower thanthat which it is tooccupywhen engaging and supporting a heel and that it should be free tobe lifted by contact with the heel of the shoe.

Being positioned as above described when a lasted shoe is being mountedupon the support 2, the roll 4 is first engaged by the rear portion ofthe heel at a point adjacent to the heel seat end of the heel and as theshoe is swung more or less in the general direction of the arrow 50 inFig. 1, in the act of adjusting the shoe firmly upon the last pin 16,the roll 4 is caused to ride upwardly along the slop ing rear face ofthe heel until it is finally elevated to the position in which it isillustrated in Fig. 1 and wherein it has adjusted itself to the contourof the vertically hollowed or concave portion at the extreme rear of theheel and serves very efficiently to support the heel against thebackward thrust of the leaflaying pad. By loosening the binding screw 36and shifting the stud 32 longitudinally in its socket, the roll may beconveniently adjusted either forwardly or rearwardly in accordance withvariations in the size and style of the heel to be operated upon,thereby adapting the roll rigidly and reliably to support the heel.

The leaf-laying pad 6 is made of yielding resilient material such assoft rubber and depends from a carrier 52 which overlies the rear of theshoe, the pad being rigidly secured to said arm in'any suitable manner.The pad 6 is so shaped that when swung downwardly it may be broughtinitially into contact with the shank of thesole at a single point onlysuch as that indicated at 54 in Figs. 1 and 4, this point being locatedsomewhat forwardly of the split portion of the shank and centrally ofthe transverse arch thereof. The movement of the pad 6 is then continuedin-the same general direction and thereafter it is rocked about its areaof contact with the sole, as will hereinafter be described, so that thepad is compressed against the shank and heel breast. The shape of thepad is such that as it is thus actuated and compressed, it will functionto apply pressure to the leaf so as to lay it progressively rearwardalong the shank and heel breast to the top-lift end of the breast andalso progressively outward from the longitudinal median line of theshank to the opposite lateral edges thereof.

To enable the pad 6 to lay the breast leaf in the manner abovedescribechthe pad-carrying means and the actuating mechanism thereforare constructed and arranged as follows: The pad carrier 52 is of theirregular shape shown in Fig. 1, comprising a depend ing leg 60 towhichthe-pad is secured and a rearwardly extending curved leg 62 which liesbetween a pair of supporting arms64, the latter being arranged parallelto each other and pivotally mounted at theirrear extremities upon spacedapart but axially alined studs 66 that are fixedly secured in upwardextensions 68' of the frame 8. The opposite end portionsof thecarrierleg 62 are slotted, as shown at 70, to receive bolts 72 whichextend transversely through the supporting arms 64 and connect thelatter to swing Vertically in unison about the pivot studs 66. The slots70 are elongat'ed' lengthwise of the carrier leg 62 and are of arcuateshape, the longitudinal center lines of the slots having the same radiusand a common center of cur vature which is located preferably somewhatbelow and at the rear of the heel'breast when the pad 6 is depressedinto its operative posit on in engagement with the sole. The bolts 72extend loosely through the arcuate slots 70 and the above describedshape and arrangement of the slots is such as to permit rearwardmovement of the pad-carrier 52 relatively tothe carrier supporting arms64s0-as to rock the pad rearwardly after the leaf has been laid againstthe shank portion of the sole to cause the rear face of the padto pressthe remaining unattached end of' the leaf against the heel-breast willbe hereinafter more fully described.

To move the pad 6 into leaf-laying engage ment with the shoe, thesupporting arms'64 are swung downwardly in'unison about their axiallyalined pivot studs 66 intotheiposition shown in Fig. 4, and at thecompletion of the leaf-laying" operation, the pad 1s returned to theposition shown in Fig. 1 by acorresponding upward movement of saidsupporting arms. The supporting. arms 64 arelowered and raised bycam-actuated means compris ing a lever 7 4 and a connecting rod 76 whichconnects the forward end of said lever with the arms 64, the upper endof said rod carrying a yoke 78 the sides of which lie adjacent to theouter sides of the arms 64 and are pi votally connected therewith by therearnrost bolt 72. The-lever 74 is fulcrumed at its rear extremity upona fixed rod 80 and carries a cam roll 82 which rides in a groove 84formed in a cam disk 86, the latter being fixed upon a cam shaft 88 thatis journaled in suitable bearings in the sides of the frame 8. The camshaft 88 is driven from the armature shaft 90 of the motor 12 through atrain of gearing comprising a pinion 92 that is fast upon the motorshaft 90, an idler pinion 94 that is suitably mounted upon the frame 8,and a gear 96 which is loosely mounted upon the cam shaft 84 and isadapted to be connected therewith by means of a foot-controlled clutch98.

As shown, the clutch 98, comprises a member 100, (Fig. 8) whichpartiallyencircles the shaft 88, and is provided with a pin 102 that is arrangedto slide freely through a collar 104 fixed to the shaft 88. The pin 102is adapted to be interposed in the path of movement of a pin or lug 106carried by the hub' of the gear 96. The clutch member 100 is normallymaintained by a spring (not shown) in a position to connect the drivingpulley operatively to the drive shaft. An inclined cam face 108 on theclutch member 100 operates, upon engagement with the upper end of abell-crank lever 110, (see also Fig. 1) to disconnect the clutch member100 and the shaft 88 from the driving? gear 96. The'lever 110 is mountedto rock upon a fixed pivot stud 112 andis-arranged to be actuated by atreadle-rod 114, a suitable spring (not shown") being utilized whichtends normally to holdthe upper extremity of the bell-crank lever 110 inengagement with the cam face 108 to hold the driving clutch member 100disengaged from the driving gear 96. The clutch 98 is actuated tostartthe machine by depression of a foot treadle (not shown) connected to thelower endof the rod- 114.

As the supporting arms 64 swing downwardly to bring the pad 6 intoengagement with the shank of the sole at the point 54, and furtherto'apply pressure to the breast leaf progressively rearward along theshank and also progressively outward to'the lateral edges thereof,-theposition of the pad-carrier 52 relatively to thesupportingi arms 64 remains unchanged; Thepad conforms under compressionto boththe'longitudinal concavity and the transverse convexity of the shank andfunctions to lay the'breast leaf progressively rearward from the point54 and also outward at both sides of the longitudinal median line of theshank so that the leaf is subje'cted to what is, inelfect, both alongitudinal and transverse rolling action. This is due partially to thepath of movement of the pad relatively to the shoe and partially to thepeculiar shape of the lower face of the pad and the angle of presentmentof said face to the sole whereby the pad is compressed into conformitywith the contour of the shank as above described. It will be understoodthat although the action of the pad is not a wiping or rubbing actionthe pad functions effectually to smooth out any wrinkles which mayextend lengthwise or crosswise of the shank. The rear portion of thelower face of the pad 6 is shaped so as to conform readily undercompression to the concave curvature of the heel breast adjacent theshank. I/Vhen the pad 6 has been depressed to the limit of its downwardmovement, it appears substantially as shown in Fig. 5, the breast leaf24: being held under pressure against the shank of the sole and upwardlyto a certain extent along the curved base portion of the heel breast. Itwill be noticed, however, that the rear face of the pad 6 is not inpressure-applying engagement with the greater portion of the heel breastand that the leaf has not yet been laid thereagainst.

After the pad has been depressed by the above described downwardswinging movement of the supporting arms 6A, the pad carrier 52 is movedrearwardly, relatively to the supporting arms 64;, to cause the pad tobe rocked backwardly about a substantially fixed point adjacent to thebase of the heel breast to apply the unattached end portion of thebreast leaf to the relatively flat portion of the heel breast and topress it into the recess or scallop 116 at the tread face end of thebreast.

To effect this backward rocking of the pad,the pad-carrier 52 isconnected by a link 118 with the upper extremity of a cam lever 120which is fulcrumed upon a rod 122 that is fixedly supported at its endsin the side members of the frame 8. At its lower end, the lever 120carries a cam roll 12% which is received in a cam groove 126 in the camdisk 82. The lever 120 and cam groove 126 are so designed that while thepad 6 is moving downwardly into engagement with the shoe, and at alltimes except while the pad is being rocked by the action of the camlever 120, the axis of the pivotal connection between said lever and thelink 118 is coincident with the common axis of the pivot studs 66 aboutwhich the pad carrier supporting arms 64 are swung. Thus the pad is freeto move into its initial engagement with the shoe without its movementbeing influenced or modified by the connectiorlis between thepad-carrier and the cam dis z. 7

After the leaf has been laid against the shank portion of the sole,however, the pad is rocked by the action of the cam lever 120 as abovedescribed to complete the leaf-laying operation. This rearward rockingof the pad 6 moves it into the position shown in Fig. 6. In moving intothis position the pressure of the compressed pad is concentrated at theportion of the shank close to the base of the heel breast and along theadjacent curved portion of the heel breast. The angle between the rearface of the pad and; the opposed breast face of the heel is graduallyclosed and the breast leaf is laid progressively upward along said heelbreast to the tread face end thereof. The pad is laterally compressed asit is forced rearwardlyagainst the heel breast and the yielding materialof the pad is forced into the scallop or cavity 116 in the heel breastand the leaf is smoothly laid over the sides of said scallop. Therocking movement of the pad is insuflicient to relieve to an undesirableextent the degree of compression with which the leaf is held against theshank portion of the sole. After the leaf has been laid in the abovedescribed manner the pad 6 is rocked rearwardly to the position shown inFig.4 5 and thereafter is returned to the initial position shown in Fig.1, thus completing the cycle of operations of the machine. Upon thereturn of the pad 6 to initial position, the clutch 98 is thrown out andthe operation of the machine is arrested to permit the removal of theshoe and the replacement of another in position to be operated upon.

It will be understood that to obtain satisfactory results from the useof the present machine a quick-drying cement should be used upon thebreast leaf. The length of time required for each cycle of operations ofthe machine, and consequently the amount of time the breast leaf is heldunder pressure against the shank and heel breast, is determined by thespeed of the motor 12 and the ratio of the speed reducing gearingconnecting the motor with the cam shaft. By changing the ratio of saidgearing, the length of time consumed at each cycle of Operations may bevaried to enable cements of different drying or setting properties to besuccessfully employed. In practice it happen at times that the breastleaf will be curled backwardly away from the shank and heel breast moreor less when the shoe is positioned for the leaf-laying operation. Insuch cases it may be desirable for the operator preliminarily to wipethe free end of the breast leaf along the heel breast by handsufficiently to insure that the leaf will be so positioned as properlyto be engaged and laid by the pad 6.

By reason of the above-described creeping or rolling of the pad 6 overthe breast leaf the latter will be laid without being subjected to anyfrictional drag or pulling action such as would result from the wipingor rubhing of the pad over the breast leaf, and which would be liable tostretch or distort the leaf and to injure its surface inasmuch as theleaf is moistened and softened by the cement before it is laid. The leafwill be laid smoothly and without injury thereto by means of the pad 6and the results will be uniform for the various shoes operated upon.Furthermore, by means of the present power-actuated machine theleaf-laying operation may be accomplished much more quickly than byhand.
